Abstract
A measurement cell includes: an enclosure; a flexible membrane disposed in the enclosure so as to contain a hardenable material; and means for stiffening the membrane configured to assume two alternative states: a stiffness state, in which the stiffening means resist the expansion of the hardenable material during solidification; and a flexible state, in which the stiffening means exert a stress that is less than that exerted in the stiffness state allowing at least one physical, chemical or mechanical property of the hardenable material to be measured and the hardenable material to be extracted from the enclosure; the stiffening means being produced by a set of metal wires connected to a clasp configured to modify the stiffness exerted by the metal wires.
